No — unisex name

What the Data Says About No

The Social Security Administration has registered 12 babies named No between 1998 and 2010, spanning 13 consecutive years of U.S. birth records. As a girl's name, No currently falls outside the top 1,000 girls' names for 2010. The name reached its historical peak in 2010, when 7 babies received it in a single year. No is classified as unisex in SSA records: the opposite-sex variant accounts for 6 additional births since 2010.

Decade-level aggregation shows that No performed strongest in the 2010s, accumulating 7 births during that ten-year window. Across the 2 decades of recorded activity, No shows a stable profile with only moderate drift from its peak decade. Geographically, the name is most concentrated in New York, which accounts for 6 births — the largest state-level total in the dataset — followed by Arizona. In total, SSA state-level files list No in 2 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for No in our reference dataset. These figures derive from SSA's annual national and state-level name files, which include any name appearing at least five times in a given year or state-year; names below that threshold are suppressed for privacy and therefore excluded from the totals shown here. The 12 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
